FROM WIKIPEDIA
The Ruger 10/22 is a series of semi-automatic rifles produced by American firearm manufacturer Sturm, Ruger & Co., chambered for the .22 Long Rifle rimfire cartridge. It uses a patented 10-round rotary magazine, though higher capacity box magazines are also available. The standard carbine version of the Ruger 10/22 has been in production continuously since 1964, making it one of the most successful rimfire rifle designs in history, with numerous third party manufacturers making parts and accessories for upgrading and customization. The 10/22's aftermarket is so prolific that a complete 10/22 can be built without using any Ruger-made components.
